The patch is not from me, but from Gabor, added in r11894 (see https://dev.openwrt.org/changeset/11894/). Jonas I had to integrate the original patch from Gabor, added in r11894 as described above, but also another one from Gabor too, added in r22861 (see https://dev.openwrt.org/changeset/22861/) to fix erase operation on the pm25lv flash chips, as in these chips, PMC is using a vendor-specific sector erase command. Although it has been verified on many devices it wasn't the same case for the newer pm25lq032 chip, it was not until yesterday that I was able to find the corresponding device datasheet (http://www.issi.com/pdf/Pm25LQ032C.pdf) to confirm that the standard sector erase command was supported indeed. Actually, both the standard (20h) and the proprietary (D7h) sector erase commands are supported, see datasheet page 12. This datasheet wasn't easy to find, since PMC has been renamed to Chingis Technology Corporation after a trademark dispute with PMC-Sierra (http://www.chingistek.com/tw/news_02.asp?seq=6), then acquired by ISSI (http://phx.corporate-ir.net/phoenix.zhtml?c=68026p=irol-newsArticleID=1716323).

Applied in r36296, thanks! -- Florian ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
